Yaz and Yasmin manufacturer Bayer is under fire yet again, this time for withholding key data about blood clot risks from the FDA. We decided to see how Bayer stacked up against other manufacturers where evil is concerned.

Ortho-McNeil-Janssen (part of Johnson & Johnson)

Evil activities: accused of hiding risks of Ortho-Evra patch, including a potentially higher risk of blood clots than that posed by birth control pills; allegedly paid kickbacks to pharmacy Omnicare to get more nursing home residents on its drugs
